What is the 3D scanning

Up to now we have utlilizzato a normal scanner to scan paper documents and, returning in digital form on paper and modifying images and text by means of special software; the principle of processing the 3D scanner is the same, but varies technology.
It 's so you can plan backwards (Reverse Engineering), ie, the object will return to the project.
The object is viewed with a special device on the axes XYZ emitting a laser pulse detects that the distance between the device and the surface of each model; each pulse will be scanned by special software before being made ​​visible on the screen.
When done we will have a 3D digital model identical to the real object, ready to be modified and be passed to the printing process.
